Y., assignors toSeal-O-Strain Corporation, a kcorporation of New York ApplicationFebruary 26, 1942, Serial No. 432,464 s claims. (C1. 21o-166) Thisinvention relates to what are commonly referred to as iilling devicesused in conjunction with tanks or containers of various types and kindsin the transmission of fluids from one tank or container to another,such, for example, in the transmission of fuel, fuel oil and other uidsof this type and kind, particularly where the straining of the fluidtransmitted is desirable. More particularly the invention relates tofiller and strainer devices employing single inlet and outlet passages,each havin-g a 'dual valve, and said dual valves controlling independentpassages through the device whereby a substantially constanttransmission of fluid may be performed, while at the same timeintermittently cleaning strainer devices in the separate passages; ofthe device to maintain uninterrupted or retarded transmission ofstrained fluid. The novel features of the invention will be bestund'erstood from the following description when taken together with theaccompanying drawing in which certain embodiments of the invention aredisclosed and in which the separate parts are designated by suitablereference characters in each of the views, and in which:

Fig. 1 is a longitudinal sectional view through' a device made accordingto my invention, the section being substantially on the broken line I-Iof Fig. 2.

Fig. 2 is a transverse sectional vievv on the line 2-2 of Fig. l, and

Fig. 3 is an end and sectional view substantially on the broken line 3-3of Fig. 1.

In the use of what is commonly referred to as lling devices or caps, andparticularly devices of this kind using strainer devices to strain fluidtransmitted therethrough, it hasbeen the common practice to shut off thetransmission of fluid intermittently to clean' the strainer employed orto substitute a new strainer, and this often times f one common end ofeach passage opening into a single intake controlled by two valves, andthe other end opening into a common discharge end controlled by twovalves. Means is also provided Vwhereby the valves controlling theseparate passages may be retained-in closed position so that eithervalve may be operated, and`further in the provision of means for quicklyremoving the strainer from the other unused chamber thereb facilitatinga constant transmission of fluid through the device from thereceivingend of the discharge end thereof. It is also a ieatureof ourvinvention to provide means securely retain,- ing the valve, release ininoperative positionvand against unauthorized manipulation. thereby ef,-fecting a positive seal and closure for the supply or storage tankcontrolled by said device.

In the accompanying drawing one adaptation of the invention isdisclosed, and in the several figures, Il) represents the casing ofthedevices Which-is more orless oblong in form and is divided by acentral longitudinal partition II into two transmission chambersorpassages I2, I2d, which are also divided intermediate the closed endWall I3, and the wall having thevlarge openings iii therein, by atransverse partition wall I5. VThe partition I5 divides the casing. intoan admission end portion I6, and discharge end portion I'l opening intothe separate chambers I2,L IZd. At the admission end areintakeports I8,I-Sa, in which are supported valve seat rings I9, having webs or arms20, supporting a bearing collar 2I, for the stems 22 of valves 23. Thevalves 23 are normally held seated upon the rings I9,by springs 24seating on the bearings 2| and on discs 2E secured to the stems 22. Thestems 22 are also guided and supported Vin bosses 26 formed in an inlethousing 21, detachable with respect to the inlet end I6 vof the casing.The housing 2l has a coupling ilange 28 around the inlet port 2S of thehousing for attaching the housing to any suitable support which might bea pipe, or' infact, this flange may be directly coupled to a tank.' .Asboth valve units are of the same construction, the brief description ofone applies tothe other and this will also apply to the dual valvescontrolling the exhaust port 30 formed in the exhaust housing 3| whichis coupled with the exhaust end I'I of the casing. Y l,

The housing 3| is substantially the same asthje housing 2'I insofar asopening intothe chambers or passages I2, I2a is concerned. The casing "Ihas two ysimilar exhaust ports 3 2 in which are arranged lvalve ringyseats 33 upon which 'exhaust valves 34 are seated. The stems 35 of thevalves operate in bearings 136' carried by arms or websl integral withthe rings 33. Springs 38 are arranged on the stem 3.5v to normallysupport the valves 34 in seated position. 'The housing 3i is alsoflanged centrally as seen at 39 for attachment to any suitable support,or this flange may serve as means for coupling transmission tubes orpipes with the tank or container to be filled.

Arranged in the discharge end I1 of each chamber or passage I2, I 2a isa long thimble shaped strainer 40, the opening end of which carries aring 4I, seating in the partition I5. A plurality of webs or spokes 42extending radially from the ring 4l supports a central hub 43, withwhich is slidably coupled a rod 44. The outer end of the rod is securedto a cover 45 which is firmly secured in position and readily detachedby a clamp arm 46 pivoted at one end to the casing as seen at 41, anddetachably coupled with a pin 48 on its other end. The central portionof the arm 46 supports a screw 4,9, having a large operating handle 50,and the screw is adapted to apply pressure to the closure plate 45, asclearly seen in Fig. 1, in retaining the plate in position. As eachclosure plate and securing means is of `identical construction, againthe brief description of one applies to both and this is also true ofthe strainer and other parts.

In order to compensate for proper seating of both the strainer and theclosure plate, the strainer is capable of sliding movement on the innerend of the rod and is held by the spring 5I in secure seated position. Acollar 52 on the inner end of the rod serves as a means engaging thestrainer to withdraw the same through the opening I 4 when the closureplate or cap 45 is removed.

The housing 21 is provided at one side thereof and in alignment with thestems 22 of the valves 23 with bosses 53. In these bosses are rotatablysupported lock rods 54 having offset crank-like lock arms 55 at theirinner ends adapted to engage the discs 25 to normally retain the valves23 in seated position and against accidental opening. The rods 54 passoutwardly through stuifing boxes 56 and have at their outer ends, heads51, by means of which the rods may be rotated to move the lock arms 55into operative and inoperative position-s. The heads 51 carry offsetlatch arms 58 cooperating with latch lugs 59 on the housing 21 tojointly receive a pad lock or other key controlled device 60 topositively retain the lock arm 55 in operative position. At this time itwould be well to say that the primary purpose of the lock SI1 is toprevent tampering with any type of storage supply of fluid in the periodof transportation or storage to prevent unauthorized removal of thefluid through the device. The head 51 of the rod 54 also has a finger 6Iwhich may be used to limit inward sliding movement of the rod andfurther as a gauge means controlling opening movement of the valve 23whenever it may be desirable to limit this opening movement of thevalve.

In the use of the filling and strainer device the fluid to betransmitted therethrough from the inlet housing 21 to the outlet housing3| is-rst passed through one of the chambers, for example, the chamberI2, and this is accomplished by releasing the lock 55 from the inletvalve 23 which opens into the chamber I2. Thus, as fluid is forced underpressure into the housing 21, the same will automatically open thevalves 23 against the action of the spring 24 and admit the duid intothe chamber I2, from which it will pass through the strainer 40 into theexhaust end I1 of the chamber I2 and out through the valve 34,registering with said chamber, the valve 34 being unseated by thepressure of the fluid as will be apparent. At this time it is well tomention that both the valves 34 and 23 are automatically seated againstany back pressures. In the transmission of a large quantity of fluid itmay be possible that during the period of transmission the strainer 40,in the chamber I2, becomes clogged. Then the lock 55 controlling thevalve 23 opening into the chamber I2a will be moved into inoperativeposition, the fluid will then be diverted to the chamber I2a, and thenthe valve 23 opening into the chamber I2 will be again seated by thelock arm 55. When so seated, the strainer 40 in the chamber I2 may beremoved, as Vpreviously described, and cleaned and then replaced. In duetime, should the strainer 40 of the chamber I2a become clogged, then theabove operation is repeated by closing the valve 23 leading to thechamber I2a after the first mentioned valve has been opened to thecham.- ber I2. Where iiuids transmitted require an excessive amount ofstraining, the above operations may be repeated a number of times in theVtransmission of one bulk or volume of fluid from a large tank orstorage. It will bel apparent that even though clogging of the strainersmay take place, quite often the quick attachment and detachment of thestrainers which is provided will satisfy any requirement to which theinvention would be applicable.

In the operation of shifting the transmission of uid from one passage tothe other, no time factor is lost, in that the operation of the lock arm55 controlling the valves may be conducted simultaneously in shiftingone valve to an open position and the opposed valve to a closedposition.

In the accompanying drawing the particular fastener means employed forsecuring the housings in position are omitted as in fact they form noparticular p'art of the invention. It will be understood, however, thatthis housing will be secured to the casing I0 in the usual or anydesired manner.
